At least 70% of Australia’s school students use computers. As a result of this increased usage, Physiotherapists are treating more young patients suffering from the effects of working at computer stations that are either designed for adults or poorly designed for children. Many children are already suffering from repetitive motion injuries such as carpal tunnel syndrome and chronic pain in the hands, back, neck and shoulders.
Our backs have three natural curves, cervical, thoracic and lumbar. They rely on proper posture to maintain these curves. Good posture remains crucial from childhood into adulthood, because proper alignment allows our spines to do what they were designed to do. When the three curves aren’t supported properly, muscles and ligaments must do the work the spine should be doing. This, in turn, puts stress on those over-taxed body parts.
Emphasis needs to be placed on teaching children how to properly use computer workstations. Poor work habits and computer workstations that don’t fit a child’s body during the developing years can have harmful physical effects that can last a lifetime. Parents need to be just as concerned about their children’s interaction with their computer workstations as they are with any activities that may affect their children’s long-term health.
To reduce the possibility of your child suffering painful and possibly disabling injuries, Physiotherapists suggest the following tips:
* If children and adults in your home share the same computer workstation, ensure that the workstation can be modified for each child’s use.
* Position the computer monitor so the top of the screen is at or below the child’s eye level. This can be accomplished by taking the computer off its base or stand, or having the child sit on firm pillows or phone books to reach the desired height.
* Make sure the chair at the workstation fits the child correctly. An ergonomic back cushion, pillow or a rolled- up towel can be placed in the small of the child’s back for added back support. There should be two inches between the front edge of the seat and the back of the knees. The chair should have arm supports so that elbows are resting within a 70 to 135 degree angle to the computer keyboard.
* The child’s knees should be positioned at an approximate 90 to 120 degree angle. To accomplish this angle, feet can be placed on a foot rest, box, stool or similar object.
* Reduce eyestrain by ensuring there is adequate lighting and no glare on the monitor screen. Use an anti-glare screen if necessary.
* Limit your child’s time at the computer and make sure he or she takes periodic stretch breaks during computing time.
* Urge your child’s school to provide education on correct computer ergonomics and to install ergonomically correct workstations.
Additionally, postural abnormalities in adolescent years have been recognised as one of the sources of pain syndromes and early arthritis in adulthood. Therefore, posture should be checked and corrected in children before more serious problems can occur.
